You can use the FFT mode to convert a time-domain signal into its frequency components
(spectrum). You can use the FFT mode for the following types of analysis:
To use the FFT mode, you need to click “Menu->Utility->FFT” to open the FFT setup window.
The FFT setup window:
You can select the Source channel, Window algorithm, FFT number, and FFT Zoom factor. It
displays only one FFT spectrum at a time.
Source
:
Selects the channel used as the FFT source
Window:
Selects the FFT window type
The windows reduce spectral leakage in the FFT spectrum.
No. of Freq Bins:
Selects the FFT number
